Jedi Master, Battlemaster, Swordsmen, Kyle Katarn
Kyle's lightsaber form. As the battlemaster of the NJO Kyle was a master of the new forms of the order and used them effectively during the Cult of Ragnos Crisis and during invasion of Yavin 4 carried out by Desann, his skill with the blade earned him the praise of the dark lord of the sith Darth Caedus who considered Kyle a viable threat. Kyle was a master of The Medium style, the fast Style, and the Strong Style and was taught the Djem So form by Luke.
Kyle's Force Powers. A man strong in the force, Kyle was a self made jedi, having been taught by the force spirit of the jedi master Qu Rahn, Kyle was able to channel both sides of the force and was a practiced hand at force lightning at times being able to send normal troopers flying back, and his force choke was immensely strong as he was able to pick Tavion Axmis with ease and was able to chain his force choke and force push and pull and was able to send his opponents crashing onto a surface, he was a proficient user of the force protect ability as shown during his mission to Vjun with his protégé and was also capable of using the force absorbtion ability and utilized the ability against various dark Jedi's during his missions to Vjun and Taspir III and was capable of using the light-sided ability, Force Heal to mend his wounds.
Jedi Knight, Swordsmen, Hero, Protégé. Jaden Korr
Jaden Korr's Lightsaber Form. Having been the apprentice to the order's battlemaster, Jaden's skill with the saber was said to have "echoed" his master's, his skill with the saber allowed him to survive three-one-one fights this due to in no small part to his training under Kyle who had also been in similar situations. Jaden much like Kyle, was a powerful user of the Medium Style, The Fast Style, The Strong Style and Jar'Kai. Though they both share similar style, Jaden best quality in terms of lightsaber combat is his versatility as he has shown himself to be very adaptable to virtually any form and type of lightsaber - ranging from the saber staff to duel wielding to the single hilt and to even the most unorthodox of moves that Marka Ragnos himself used, something only a select few achieved.
Force Prowess/Powers. As the apprentice to Kyle Katar, Jaden like his master was able to channel both sides of the force, he was a practiced hand at force lightning, being able to send both Normal Troopers and Dark Jedi flying backwards. like katarn, Jaden was able to use force choke and hurl his opponents to any surface/thing, he was a proficient user of force protect and used it during his mission to Vjun to protect himself against the acid rain there and had great knowledge of force absorbtion using it against various dark jedi, including Tavion's apprentice, Alora, Tavion herself and Marka Ragnos when he possessed Tavion Axmis, he was master of force speed and was able to use force speed to both boost his speed in combat and escape from a crumbling tomb. Despite his already impressive pool of powers, his most powerful showing is his prowess with Telekinesis, using to blast three large cylinders out of his way, move three statues twice his size, sending a boulder flying, to open a large door and bring down a huge pillar.
Versus
Jedi master, Battlemaster. Kao Cen Darach
Kao Cen Darach's Lightsaber form. As the battlemaster of the old order I believe it would ne safe to say, he knew all forms, he seems to favor chaining force powers with his attacks which shows that he had knowledge of Niman and he also used various acrobatics during his fight with Malgus which is attributed - thought not exclusively, to Ataru. this is supported by the fact that Satale seems to use Acrobatics as well as chaining her force powers, which could be attributed by the fact that Kao Cen was her master, his skill with Niman, Ataru and Jar'Kai with a double lightsaber allowed him to go up against Lord Vindican and his apprentice Darth Malgus.
Force Prowess/Powers. Unlike other jedi battlemasters - cough Cin Drallig cough Raskta Lsu cough, Darach was a practiced hand at Telekinesis, using it to lift heavy rubble and ship parts and hurling them at his target, he was capable of unleashing a surge of force power when he punched the ground during his battle against Vindican and Malgus.
Hero, Icon, Savior, Grandmaster, Descandant of Revan and Bastila. Satale Shan
Satale Shan's Lightsaber forms. As a former student of Kao Cen Darach, Satale - much like her master, utilized Ataru and Niman to great extents, using the forms against the dark lord Malgus and many Dark Jedi, she utilized many lightsabers, which shows that she is very versatile and is not afraid of the unorthodox.
Force Prowess/Powers. As the decendant of the shan family, Satale is extremely strong in the force and the grandmaster of the order Stale was capable of using her unorthodoxy to her advantage, she was a master of Telekinesis having brought down an entire mountain top on darth malgus leaving him severely injured, she was able to form a protective bubble while in space, she could block lightsabers with her bare hands, She even had great knowledge of Shatterpoint.
